Hi All,
Is there something like the GNU-GSL in Free Pascal?
I'm looking for statistical functions like inverse beta distribution.
Some-when, I re-implemented some functions from C, but don't
want to reinvent the wheel the nth time.
regards
M. Schäfer

Have you seen these?

there's also Amath http://www.wolfgang-ehrhardt.de/misc_en.html#AMath

I just took a quick look at DMath l looks good.
I will also check AMath.
Thanks for help

There is a inverse regularized incomplete beta function in numlib. Afaik not for the normal beta function.
Have a look, they are in unit "spe" in the numlib package

Hi, do you achieved a full success? In Pascal I was able to create all functions (pdf, cdf, inverse cdf) for many somewhat difficult functions (like chi2, student-t, etc.), BUT still I found no solution for inverse cdf for beta distribution and e.g. generalized Gaussian type1 or generalized T. Has anybody also these?
I found some math units which should have the required functions, but none worked so far for inverse cdfs.
